SERVER
Server Processors
• Server processors generally have more cores than desktop
processors in the same class, allowing them to complete more tasks
simultaneously.
• Most servers use more than one processor.
• Multiple processors allows the server to keep running in the event
that one of its processors fails.
Server vs. Desktop
• Validation
•
Server processors are put through all kinds of tests under stressful
conditions such as higher temperatures, strict environmental conditions, and
high computing loads.
• Dependable
•
Server processors are designed for reliability. For example, if your desktop
processor were to somehow fail, the whole workstation becomes
inoperable. Server CPUs have the smarts to be able to failover, in the case of
a dual CPU server, without having to crash or shutdown.
Server vs. Desktop
• Higher trafficking
•
Server CPUs are designed with buses that operate at much higher
frequencies (bandwidth). This means that they can process more data in and
out of memory and other subsystems.
• Self Correcting
•
Server processors have the circuitry in place to correct memory errors that
can affect stability. The technology is called Error Code Correction (ECC).
Intel Xeon Processor
• Intel Xeon is a high-performance version of Intel desktop processors
intended for use in servers and high-end workstations.
• Xeon CPUs have the same features as Pentium 4/D, Core 2
Duo/Quad desktop microprocessors.

Snapdragon 800
News Flash: ZTE Grand Memo was just announced to be the first device to
use the Snapdragon 800
ZTE Grand Memo
Asynchronous Symmetric Multiprocessing
Qualcomm custom designed their own microarchitecture,
called “Krait,” based on the ARM instruction set.
Technology can throttle the frequency of each CPU core
independently, which makes the design more power efficient.

Variable Symmetric Multiprocessing Architecture
Variable SMP architecture enables four performance cores to be
used for max burst, with each core independently and
automatically enabled and disabled based on workload.
2MB L2 cache can be dynamically allocated to any CPU
